High Pressure Relief Valves

High Pressure Relief Valves

High pressure relief valves are designed to release fuel back into the fuel tank should a over-pressure situation occur. Senior Flexonics designs, manufactures and tests their single stage and dual stage relief valves.

Senior Flexonics’ investment in their test facilities is unique in the industry. Our new valve test bench enables our Engineers to test and validate our single and dual stage high pressure relief valves. Our valve test bench has the capability to perform three critical tests including: Cycling test cracking pressure, Cycling test working pressure, and sealing test.
